What do I do if I accidentally upgraded my turbotax account?

TurboTax has 2 free products, but you are not in one of them.  You appear to be using Live Basic Edition, which is a paid version--$80 for Federal and $45 for state (if applicable), and if you choose to pay the fees out of your Federal refund, there is an additional $40 service fee ($45 for California filers.)   I'll tell you about both free products below.   Read this whole long post before making a decision.

The Live Basic edition is an upgraded version of Free Edition that has live on-demand help from a CPA/EA tax expert during return preparation and a review of your return prior to filing.  It adds considerable cost to the return, unless you want that feature.     Here's how to remove the Live upgrade and go back to regular Free Edition:

The regular Free Edition is for very simple returns and not everyone can use it.  Certain forms are not available in Free Edition and require an upgrade to Deluxe or higher, such as one of Schedules 1-3, itemized deductions, education credits, student loan interest, retirement savers credit, etc.   See this FAQ on some situations where one cannot use Free Edition:

You may be able to get back to Free Edition by using the first FAQ above on how to remove Live.

The other free product (TurboTax IRS Free File Program) is fully-featured and can prepare all the usual forms and schedules.  It is even more powerful than Deluxe, if you qualify.  For example, in addition to Schedules 1-3 it can prepare Schedule C, D, E, F, etc., and enter K-1. But one has to meet one of the qualifications to use.  See below:

To qualify for free 2019 federal and state tax returns through the IRS Free File Program delivered by TurboTax, you just need to meet one of these requirements:

• You qualify for the Earned Income Tax Credit (EITC); or
• In 2019, you served as active duty military (including Reservists and National Guard) with a maximum AGI of $69,000, and you have a military-issued W-2.
